Order by date

Hi,

I am trying to create a site which displays news from different sources. I have the news articles in a MySQL database. On the list.rhtml page I display the news articles but they are stored in the db in no particular order. How do I get ruby to order these by date, newest first, when they are displayed?

Thanks, Lewis

Thanks, my model is named feeditems and the timestamp column is called publishdate.

How do I update the code to reflect this?
